STUDER INNOTEC

Safety

The inverter is electronically protected. But protection against polarity inversions of the
battery occurs with an internal fuse, except for AJ 2100-12 inverter, which has no
fuse. The following table will show you the different failures and their consequences.
FAILURE
Low battery voltage
Voltage < 1.8V/cell
Deep discharged battery
(voltage <1,5V/cell)
Overheating
Battery over voltage
Short circuit in the outlet
Overload
Inversion of the battery
polarity
CONSEQUENCE
Inverter momentarily
stopped, the green
indicator blinks.
Inverter stopped
Inverter momentarily
stopped, the green
indicator blinks.
Inverter stopped.
Inverter stopped.
Inverter stopped.
Internal fuse broken down
AJ V2.1
SOLUTION
Automatic restart when the
battery voltage rises
Inverter should be manually
restarted when the battery
as reach 2V/cell
Automatic restart when the
temperature reaches the
normal range.
Wait until the battery voltage
reaches the correct level.
Push the ON/OFF switch to
reactivate the inverter
Eliminate the short circuit.
Push the ON/OFF switch to
reactivate the inverter.
Use the inverter only in the
range of its nominal power.
Regular use in overload
power diminished the
lifetime of the inverter.
Push the ON/OFF switch to
reactivate the inverter.
